Abstract

A method of locating an object across a network comprises locating the copy of object 5 that is the best copy available through either JNDI object location and webservice location. In one advantageous embodiment, the method initially comprises attempting to locate a local copy of the object (step 8). If a local copy of the object is not located, the method 10 then attempts (step 10) to locate a remote copy of the object. If a remote copy of the object is not located, the method then attempts (step 12) to locate a remote web service object.

Claims

1. A method of locating an object across a network, the method comprising:

locating the copy of the object that is the best copy available through either JNDI object location and webservice location.

2. A method as claimed in claim 1 and comprising, in response to a request for an object:

carrying out a Java Naming and Directory Interface (JNDI) search for the object;

if the JNDI search locates a copy of the object, retrieving the copy located by the JNDI search;

or

if the JNDI search does not locate a copy of the object, attempting to locate a remote web service object.

3. A method as claimed in claim 2 and comprising, if a remote web service object is located, retrieving the copy of the remote web service object located.

4. A method as claimed in claim 2 wherein carrying out the JNDI search comprises:

attempting to locate a local copy of the object;

if a local copy of the object is located, retrieving the local copy of the object;

or

if a local copy of the object is not located, attempting (step 10) to locate a remote copy of the object.

5. A method as claimed in claim 4 and comprising, if the search locates a remote copy of the object, retrieving the remote copy of the object.

6. A method as claimed in claim 1 and comprising attempting to locate a requested object in a cache before attempting to locate the object through either JNDI object location or webservice location.

7. A method as claimed in claim 1 and comprising caching a retrieved object.

8. A network node for locating an object across a network, the node being adapted to locate the copy of object that is the best copy available through either JNDI object location and webservice location.

9. A network node as claimed in claim 8 and adapted to:

carry out a Java Naming and Directory Interface (JNDI) search for the object;

if the JNDI search locates a copy of the object, retrieve the copy located by the JNDI search;

or

if the JNDI search does not locate a copy of the object, attempting to locate a remote web service object.

10. A network node as claimed in claim 9 and adapted to carry out the JNDI search by:

attempting to locate a local copy of the object;

if a local copy of the object is located, retrieving the local copy of the object;

or

if a local copy of the object is not located, attempting to locate a remote copy of the object.

11. A computer-readable medium containing instructions that, when executed on a processor, perform a method of locating an object across a network, the method comprising:

locating the copy of object that is the best copy available through either JNDI object location and webservice location.

12. A computer-readable medium as claimed in claim 11, the method comprising, in response to a request for an object:

carrying out a Java Naming and Directory Interface (JNDI) search for the object;

if the JNDI search locates a copy of the object, retrieving the copy located by the JNDI search;

or

if the JNDI search does not locate a copy of the object, attempting to locate a remote web service object.
